Hi guys i'v got my engine stripped at the min its got hks cam's in how can i tell if its got uprated spring and retainer's in? Also its got hks stamped on the cam's how can you tell what profile they are as i can't see any number's? Regard's steve.
not many people fit up rated springs with hks 264 or 272 , 10.8 isnt stamped on the cams . iirc theres a number stamped on either the end face on exh cam where the cam sensor disc bolts on or other end on the upper edge near the first bearing face .
